Modeling and Enforcement of Cloud Computing Service Level Agreements
A Service Level Agreement (SLA) defines the contract between a cloud provider and a cloud customer, detailing the resources being provided, the price the user will pay, and the quality of service (QoS) guarantees that the cloud provider ensures for the customer. If the QoS guarantees are not upheld, typically the cloud provider is assessed some penalties, such as payment credit for the customer...
متن کاملCultural Differences in Managing Cloud Computing Service Level Agreements
Software as a service and cloud computing are new buzzwords in the Internet-based economy. Their idea is to provide software, computing and storage capacity in large, but yet unknown numbers. The legal basis of offering such services is provided by service level agreements (SLAs). In a global economy, these SLAs are often made between companies based in different countries, thus between individ...
متن کاملService-Level Agreements for Service-Oriented Computing
Service-oriented computing is dynamic. There may be many possible service instances available for binding, leading to uncertainty about where service requests will execute. We present a novel Markovian process calculus which allows the formal expression of uncertainty about binding as found in service-oriented computing. We show how to compute meaningful quantitative information about the quali...
متن کاملAdding Cloud Performance to Service Level Agreements
To some the next iteration of Grid and utility computing, Clouds offer capabilities for the high-availability of a wide range of systems. But it is argued that such systems will only attain acceptance by a larger audience of commercial end-users if binding Service Level Agreements (SLAs) are provided. In this paper, we discuss how to measure and use quality of service (QoS) information to be ab...
متن کاملPrivacy and Security of Big Data in THE Cloud
Big data has been arising a growing interest in both scien- tific and industrial fields for its potential value. However, before employing big data technology into massive appli- cations, a basic but also principle topic should be investigated: security and privacy. One of the biggest concerns of big data is privacy. However, the study on big data privacy is still at a very early stage. Many or...
